Hopefully fixed an oversight with two weapon spawn points.

- Peppino's Sauce Machine is now a wave song instead of a panel song
- Spooky Apartment Escape is now a panel song instead of an escape song
- Thousand March is now an escape song instead of a panel song
- Panel music now plays if you lose and restart at the checkpoint
- Wave music now plays if you vote for and play the map again after beating it
- Added Time For A Smackdown, Pizza Deluxe, Pizza Pie-Ing, Receding Hairline Celebration Party, Choosing The Toppings, and Hip To Be Italian for use in the upcoming custom end-of-match credits function
- Added Meatophobia, Hard Drive To Munch You, Your Fat Ass Slows You Down, and Okay Campers, Rise and Shine! for use in the escape fail sequence
- Added Unexpectancy Part 3 as another escape song

NPCs
- Added 6 spawn points in tunnel 24
- Added 3 more spawn points to the lowest spot the elevator can go to/where the antlion caves end
- Adjusted the ceiling hole spawn in the same area
- Added a spawn point to a hole in the ceiling in tunnel 12
- Added a spawn point to a hole in the wall in the lower area of where tunnel 24 leads to
- Added 4 spawn points to the area with the vent to the antlion caverns
- Enemies now have FindEnemy_UseSphere and FindEnemy_CanSeeThroughWalls set to true
- Added the HLA Antlions to the npc health table
- Zombines, Tau Rebels, and Heavy Rebels can no longer spawn at spawners with the "walkers only" spawnlist
- Zombines now give 75 points instead of 50
- Adjusted Zombine item drops so you can't get two different grenade weapons
- Reduced spawn rate of HLA Antlions

Weapons/Items
- Shuffled around the hidden weapons
- Moved an mp5 mag in the area tunnel 36 leads to so it doesn't float anymore
- Moved a barrel in the area tunnel 36 leads to to a different spot
- Slightly moved a barrel in the area tunnel 24 leads to so that it doesn't clip into the wall
- Added a grenade and satchel charge pickup at the drop where the antlion caves end

Other
- Adjusted player spawns
- The escape fail sequence is now shorter
- Pizzaface's laugh now plays instead of the siren in the escape fail

Addon no longer replaces sh_music.lua and music is instead added via the map config itself.
Thanks to upset for showing how to do this.

Initial addon creation.
